Abstract

A current resonance type inverter circuit includes: a step-up transformer, a primary winding of the step-up transformer having a center tap, the center tap of the primary winding of the step-up transformer being connected to a power source side; and primary side driving method, other two terminals of the primary winding being connected to collectors of two transistors, respectively, emitters of the two transistors being connected to respective terminals of a primary winding of a current transformer having a center tap, the center tap of the current transformer being connected to a ground side, a secondary winding of the current transformer being connected to bases of the two transistors to detect emitter currents of the two transistors in order to detect a resonance current, thereby performing oscillation, in which a secondary side circuit of the step-up transformer has a small leakage inductance value, the secondary side circuit of the step-up transformer has the discharge lamp, the secondary side circuit of the step-up transformer has a distributed capacitance, a suitably added capacitor and a stray capacitance generated in the vicinity of the discharge lamp, these capacitance components are composed with one another to form a secondary side capacitance, the secondary side capacitance and the leakage inductance contribute a series resonance circuit, and the discharge lamp is connected in parallel with the capacitance components to constitute the series resonance circuit having a high Q value, whereby a high step-up ratio is obtained to turn ON the discharge lamp, and a phase difference between a voltage and a current when viewed from the primary winding side of the step-up transformer is generally small.
